The YouTube Android Player API enables you to incorporate video playback functionality into your Android applications. The API defines methods for loading and playing YouTube videos (and playlists) and for customizing and controlling the video playback experience.
Using the API, you can load or cue videos into a player view embedded in your application's UI. You can then control playback programmatically. For example, you can play, pause, or seek to a specific point in the currently loaded video.
You can also register event listeners to get callbacks for certain events, such as the player loading a video or the player state changing. Finally, the API has helper functionality to support orientation changes as well as transitions to fullscreen playback.
How it works
The API client library interacts with a service that is distributed as a part of the YouTube app for the Android platform. The client library has a light footprint, meaning it won't adversely impact your app's file size, if you use ProGuard as part of your build process.
As the API develops, you will be able to access newly introduced API features by upgrading to a newer version of the API client library. However, upgrading is not necessary if you do not care about new features or bug fixes.
In addition, the YouTube app is delivered through the Google Play Store, which means that updates to the API service are not dependent on carrier or OEM system image updates. Generally, devices running Android 2.2 (Froyo) or later that have the Google Play Store app installed will receive updates within a few days. As a result, your application can use the YouTube Android Player API and reach most devices in the Android ecosystem.
Note: Users need to run version 4.2.16 of the mobile YouTube app (or higher) to use the API.
